There’s a lot of stuff that happens in the mobile industry, something that is especially true when it comes to giants like Samsung. If you missed out on some (or all) of what happened over the weekend, well, here’s a recap of all the big things that went down.

We exclusively leaked retail images of the Galaxy Tab S, which showed off its extremely thin profile, and also revealed how Samsung intends to market the AMOLED screen on the tablet, through images that compare AMOLED displays to LCD units. A Samsung tablet with a 4K Ultra HD display was showcased and raised expectations of 4K tablets hitting markets before the end of the year. Meanwhile, a rumor suggested that Samsung is currently cutting down on orders of the Galaxy S5, as it prepares to see competition from Apple’s upcoming iPhone 6, which is expected to sport a considerably bigger screen than previous iPhones.

As usual, a lot of devices got firmware updates as well, so here’s a list of all the updates that rolled to Samsung devices over the weekend (as always, you can find all the firmware you need in our firmware section):
